Touch typing is a method of typing without using the sense of sight to find the keys. Each finger is given its own area of the keyboard, and the hands return to the home row after every stroke. Because the eyes stay on the screen, the typist can notice mistakes immediately and keep reading the source text without interruption. Research on skill learning suggests that short, frequent practice sessions are more effective than long, occasional ones. In other words, fifteen focused minutes every day will usually do more for your speed and accuracy than two exhausting hours once a week.
